422 ARANEIDEA. 
2. Frontinella bicuspis, sp.n. (Tab. XL. figg. 3, 3a, 4, 3.) 
Type, ¢, in coll. Godman & Salvin. Total length 4 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
This species is smaller than F. Jeta, and resembles it in having a small tooth at the 
base of the mandible; but may easily be distinguished by the possession of two short 
cusp-like spines at the apex of the patella of the palpus, while the palpal organs are 
much simpler (see Plate). 
3. Frontinella falculifera, sp.n. (Tab. XL. figg. 4, 44, 3.) 
Type, d, in coll. Godman & Salvin. Total length 7 millim. 
Hab. Costa Rica (Rogers). 
Easily distinguishable by the two falciform processes lying on the palpal bulb. The 
patella of the palpus bears only one cusp at the apex, and there is no tooth at the base 
of the mandible. 
4. Frontinella uncata, sp.n. (Tab. XL. figg. 5, 5 a-c, 6; 6, 2.) 
Type 3, gynetype 2, in coll. Godman & Salvin. Total length, ¢ 5, 2 4 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith); Guatemaa, Cubilguitz (Sarg) ; 
Panama, Bugaba (Champion). 
Recognizable by the form of the embolus and conductor of the male palpus and by 
that of the vulva in the female. 
5. Frontinella tibialis, sp. n. (Tab. XL, figg. 7, 7 a, b, 3.) 
Type, d, in coll. Godman & Salvin. Total length 4°5 millim. 
Ilab. Mexico, Teapa in Tabasco (H. H. Smith). 
The form of the processes of the bulb of the palpus, as well as the much oreater 
relative length of the tibia, will enable this species to be recognized.

In dealing with Linyphia communis, Hentz, I here regard Emerton’s identification 
of the species as correct. ‘This author’s figures show that the palpal organs resemble
